SHAPING-MACHINE.

To all whom 'it may concern:

Be it known that I, FREDERICK L. EBEE- HARDT, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Shaping-Machines; and I do hereby declare the following specification, taken in connection with the drawings forming a part of the same, to be a full, clear, and exact description of the principle of said invention and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The invention relates primarily to metal working machines having a reciprocating tool slide, and more particularly to shaping or slotting machines in which the tool-slide or rain is arranged to reciprocate wit-hin rectangular guides.

The object of the present invention is to provide rectangular guides, of rigid construction, for the reciprocating tool-slide to better resist the deflections imparted by the cutting action of said tool and to produce work with a greater degree of accuracy.

Another feat-ure relates to means for clamping the guide blocks securely to the frame, comprising a series of studs arranged in close proximity to the guides of the toolslide, which has not been attained by the rectangular coi'istructions heretofore.

Other features relate to the adjustingl means provided to compensate for the lateral and vertical wear of said rectangular guides.

The invention comprises a frame or pillar, a tool-slide arranged to reciprocate thereon and provided with rectangular guides, guide blocks provided. on said frame and arranged to be rigidly secured thereto, and means to adjust said blocks to compensate for the lateral and vertical wear thereof.

The annexed drawings and the following description set forth in detail, certain mechanism embodying means constituting however, but one of the various mechanical forms in which the principle of the invention may be read.

In the drawings, illustrating the invention in its preferred form as applied to a shaping machine and which show so much of a shaping machine as is necessary to properly illustrate the invention, the novelty of which will Specification of Letters Patent.

Application filed August 26, 1909.

Patented Uct. 18, 1910.

Serial No. 514,835.

l be readily understood from the following detailed description and which is more particularly pointed out in the claims: Figure l, is a side elevation of a shaping machine showing the guide block and vertical adjusting means in section. Fig. 2, is a section at X X, of Fig. I, to clearly illustrate the construction of the rectangular guides. Fig. 3, is a sectional view taken similar to Fig. 2 illustrating a modification of the lateral adjusting means for the guide block and Fig. 4, illustrates still another modification of means for lateral adjustment.

Referring to the drawings, particularly to Figs. l and 2, the frame or pillar 1 incloses the gearing and lever to reciprocate the toolslide 2. Said reciprocating mechanism, for the tool-slide 2, is of the usual construction as found in shaping machines and forms no part of the invention and therefore need not be described in detail. The tool-slide Q is provided with rectangular guides C.) on each side thereof and is arranged to slide within the guide blocks #l which are interposed between the projections 5, the frame and said tool-slide 2. The guide blocks 4 are shaped like an inverted L and rest at each end upon the taper gibs G provided between said blocks 4 and the frame l. The taper gibs G are adjusted by means of the adjusting screws 7, to take up the vertical wear of the tool-slide guiding surfaces. Studs S, are arranged within the frame, and in close proximity with the tool-slide guides 3, to securely clamp the guide blocks 4, and the taper gibs 6, to the frame l, when properly adjusted. An angle 9 is arranged upon one or both of the frame projections 5, of such magnitude as to compensate for the lateral Wear when the guide block 4t is adjusted to take up the vertical wear In Fig. 3 the lateral wear is taken up by the twvo taper gibs l() of similar construction and arrangement, as provided to compensate for the vertical wear. rIhe lateral adjustment in Fig. t is accomplished by the headless screws l1. This means however, has the disadvantage that the guide blocks et do not rest solidly against. the frame projection 5. The guide blocks constructed and arranged in the manner described provide a more rigid construction to resist the vertical strains of the tool-slide, than has been possible to attain with the arrangements heretofore employed in which a flat strap was l said frame thereby forming a rigid and adbolted to the frame projections and projected over the guides of the tool-slide.

Another advantage over the fiat strap arrangement is in the means of adjusting the guide blocks for vertical wear without the necessity of machining any part thereof. By interposing the guide bloclrs, as described, the same rigidity and ability to resist the lateral strains is maintained as found in the flat strap constructions.

Another important advantage obtained is in the placing of the studs 8 in close proximity with the tool-slide guides 3 so that the heads of the nuts 12 project over the edge of said guides 3. This placing of the bolts has not been attained in the flat strap constructions hereinbefore referred to, due to the necessity of allowing sutlicient metal for a backing for the threads of the studs 8. Furthermore in said construction a gib had to be interposed between the toolslide guides 3 and the frame for the lateral adjustment; this necessitated the locating of the studs on the gib side still farther away from the point of resistance.

In the invention it will be noticed that due to the construction, the studs are threaded into the fiaine below the surface of the tool-slide enabling them to be placed practically in contact with the edge of the tool-slide g'uides 3 on each side thereof.

Having described my invention, I claim as new and desire to secure by Letters Patent:

1. The combination with a frame of a tool-slide mounted to reciprocate thereon and provided with rectangular guides, guide blocks for said tool-slide, means to adjust said blocks to compensate for the lateral and vertical wear and means to rigidly secure said blocks to said frame, substantially as described.

2. The combination with a frame of a tool-slide mounted to reciprocate thereon and provided with rectangular guides, guide blocks for said tool-slide, and means to rigidly secure said blocks to said frame, thereby forming a rigid guideway for said toolslide, substantially as described.

3. The combination with a frame of a tool-slide mounted to reciprocate thereon and provided with rectangular guides, guide blocks for said tool-slide, means to rigidly secure said blocks to said frame, and adjusting means to compensate for the lateral and vertical wear, substantially as described.

4. The combination with a frame of a ltool-slide mounted to reciprocate thereon and provided with rectangular guides, guide blocks in said frame, taper gibs to adjust said guide blocks vertically, and means to rigidly secure said blocks and taper gibs to justable guideway for said tool-slide, substantially as described.

5. The combination with a frame of a tool-slide mounted to reciprocate thereon and provided .with rectangular guides, guide blocks in said frame, taper gibs to adjust said guide blocks to compensate for the vert-ical wear, means to adjust one of said guide blocks laterally to compensate for the lateral wear, and means to rigidly secure said blocks and taper gibs to said frame thereby forming a rigid and adjustable guideway for said tool-slide, substantially as described.

6. The combination with a frame of a tool-slide mounted to reciprocate thereon and provided with rectangular guides, two guide blocks for said rectangular guides, taper gibs provided on each end of said guide blocks to adjust same, thereby coinpcnsating for the vertical wear, means to adjust one of said guide blocks laterally, to compensate for the lateral wear, and means to rigidly secure said blocks and taper gibs to said frame, thereby forming a substantial.

and adjustable guideway for said tool-slide, substantially as described.

7. The combination with a frame of a tool-slide, mounted to reciprocate thereon and provided with rectangular guides, two guide blocks in said frame, a series of studs arranged in close proximity with said rectangular guides, to secure said guide blocks to said frame, and adjusting means to compensate for the vertical and lateral wear, substantially as described.

8. The combination with a frame provided with upward projections of a toolslide arranged to reciprocate between said projections and provided with rectangular guides, guide blocks interposed between said frame projections and rectangular guides to form a substantial guide for said tool-slide, and means to rigidly secure said guide blocks to said frame, substantially as described.

9. The combination with a frame provided' with upward projections integral therewith, of a tool-slide arranged to reciprocate between said projections and provided with rectangular guides, guide blocks, interposed between said frame projections and rectangular guides, and means to adjust said blocks, and secure same rigidly to the frame, thereby forming substantially a rigid and adjustable guide for said tool-slide substantially as described.
